Our invention relates to what may be termed a pantry refrigerator and ice cream cabinet more especially designed for use in railroad dining cars where the limited space in the pantry or kitchen of the'dining car necessitates a special arrangement of the refrigerator adapted to meet the restricted area and severe requirements encountered.

VThe refrigerator is especially designed for mechanical refrigeration and so constructed as to have a chilling temperature, at least in certain portions or chambers, requisite for the proper keeping of ice cream as well as ice cubes which are more or less extensively used in dining car service of Avarious commodities.

The invention also has for its'object the provision of a construction which will permit easy access to the respective compartments while at the saine time enabling full access to the refrigerating unit to be had for the line 3-3 of Figure 1 as indicated by the arrows. Figure 4 is a cross sectional view taken on the line 4-4 of Figure 2 as shown by the arrows.

Figure 5 is a cross sectional view taken on th'e line 5-5 of Figure 2.

The refrigerator in its specific embodiment as disclosed in the drawings is shown of angular formationand construction to adapt it to the comparative close quarters encountered in the kitchenof a dining cargthe refrigerator as shown being intended for 'location in a corner' of the kitchen adjacent to the partition walls. The refrigerator is preferably of such vheight as to also constitute a 10 in Figure'2 which pref- 'are preferably of sheet -above the other and mounted within the coils erably consists l of wood of suitable thickness, covered with a suitable metal such as Monel metal; the top, -sides and bottom being provided with suitable insulating material of proper thickness, as for example cork board shown at 11 arrangedand properly sealed intermediate of the outer walls of the refrigerator and the inner walls shown at 12 which may be of wood covered preferably with sheet metal.

While the refrigerator has beenl shown formed to fit into the corner of the kitchen and therefore with portions disposed parallel with two side walls or partitions, it is obvious that the general configuration of the refrigerator may vary to meet specific requirements and conditions, without sacrificing any of the advantages and without departing from the spirit of our invention.

y The refrigerator, as illustrated, has one side or section provided with a refrigerating unit holding compartment 13 completely surrounded by insulated walls, see Figures 1 and 2; the compartment being provided with the usual liquid container 14 employed in a well known type of refrigerating unit and which is provided with the dependiii g coils 15 and-16 disposed toward the bottoni ofthe compartment 13 as shown in Figure2.

We have shown certain of the coils, as for example coils 16 (of which there are a series extending from front to rear of the cylindrical container 14 with ice cream holding boxes or containers 1 The containers, of which two are shown in the specific exemplication, metal arranged one 16 to which they may be secured if desired; the containers being preferably of rectangular formation and completely closed on all sides exceptv the forwardfsides or ends which are disposed toward the door 18 (see Flgure 5) These containers are especially intended for the storage of brick ice cream, which requires a low degree of temperature in order to maintain the ice cream in proper serviceable condition.l

The door 18, like the walls of the compartment, is ,of suitable thickness so as to contain suitable insulating material 11 which may consist of corklboard sealed with a suitable non-odorant sealing cement; with the juncture between' the ldoor and side walls *made as is usual in this art to provide a more Qthickness of cork-board covered with sheet, metal and extends from front to rear of the or less air-tight closure.

The refrigerator, adjacent to the ice cream holding compartment, is provided with a separate chamber l9formed by one wall of thev ice cream chilling compartment and an insulated wall or baffle member 20.

The wall v2O preferably consists of a proper refrigerator, with an opening 21. of sufficient size above the balile or partition and an opening 22 at the bottom thereof. In practlce, the

opening 21 at the top is preferably slightly greater than the opening at the bottom. The partition or baiie separates the compartment 19 (except for the openings 21 and 22) from a refrigerant holding chamber 23. In the drawings, this chamber 23 is shown provided with a suitable mechanical refrigeratingunit 24 properly mounted'with its iincoils 25 extending downwardly toward the bottom of the compartment 23. f-

The compartment 19 is also shown provided witha number of bins 26, preferably of the somewhat funnel shape, namely with the refrigerator and ca inet is intended tothe sides converging toward the bottom; the

bins 26 being suitably fastened to the inner sides of the compartment doors 27 which latter are preferably hinged Vat bottom to the Y main outer casing of the refrigerator to swing l outwardly and downwardly, thereby bringing the bins 26 into position where access.

thereto may be readily had. The bins 26 are preferably made of sheet metal and are primarily intended Vfor storing ice cubes. The

maintained. t

In the particular ex mplification, Where extend parallel with tw`o/ side walls of a pantry or kitchen, the refrigerant holding portion 23 is shown arranged in the right angular corner ofthecabinet and the wall adjacent to partition or baiile 20 shown in the nature of an i msulated partition or baille 28 which preferably also consists of a suitable thickness of cork-board covered with` sheet metal. The partition 28 extends fromfr'ontto rear-of the refrigerator, with a suitable spacing or opening 29 at top and a spacing or opening 30 at bottom in order to permit circulation o f cold air from the refrigerant holding compartment 23 into lthe adjacent compartments- 81 .see Figure 3.. The partition or wall 28 is preferably hin edly secured at 33 to the rear Wall of the re rigerator to permit the baille or partition 28 to swing into the food holding compartments 31, 32, namely into a position against the rear wall of the refrigerator in order'that ready access may be had to the refrigerant unit 24 for servicing or removal or replacement when found necessary. The free forward end of the partitionV or wall 28 may be maintained Ain proper position in any suitable manner, as for example, by the flange or lip 34 secured to the forward wallof the refrigerator on the refrigerant holding side of the partition as shown in Figure l.

The balie or partition 28, at a suitable point intermediate of the top and bottom ends thereof, is shown provided with an angle bar or flange 35 to support a shelf member 36.A

The opposite end of shelf 36 is supported by a cleat or bar 37 extending from front to rear of the refrigerator and this bar 37 in turn supports the shelf section 38 which is also'n supported in a suitable manner on the screen partltion 39. Thisscreen partition 39 extends from top to bottom and from front to-rear of the refrigerator in suitable spaced relation with the end wall 40 of the refrigerator thereby providing an air chamber or passage 41 at the end of the compartment provided with the imperforate shelf sections 36, 38 which extend from front to rear of the refrigerator. W'ithl the construction shown, it is apparent that the cold air from the refrigerant oldmg compartment 23 will pass through he opening 30 at the bottom of thebaie or .partition 28, thence lengthwise of "compart ment 3 1 (because of the imperforate shelves 36, 38) through the wire mesh partition 39,

into passage 41, and thencel upwardly and lengthwise through compartment 32, returnas at 42, see Figure 1;thus allowing the ing into the refrigerant holding compartment les baie or partition 28 tobe swung against the rear wall on the hinge -connection 33.

It will be understood, of course, that the 'various doors of the refrigerator are of proper insulated construction and formed to effect air-tight-closures as is usual in refrigerator construction.. With the ice cubeholding bins 26 secured to the inner sides of the doors 27 (which are preferably hinged at their lower ends) these doors will be held tightly closed by the weight of thel bins and their contents.

It is obvious that although the refrigerator andcabinet has beenl shown of right angularconstruction to adapt it to the limited space of a dining car kitchen, the refrigerator may be of any suitable configuration or shape involving the particular arrangement of 'compartments heretofore described which are especially adapted to the uses for which our improved refrigerator is intended, being provided with means-for the special handling and storage of ice cream 'and ice cubesy in compartments which are preferably independent of each other, in conjunction l invention.
